-------------------------------------------
Summary: CDC batch-write mixing a CDC-enabled and CDC-disabled
table drops the CDC table's mutation
Key: CASSSIDECAR-499
URL: https://issues.apache.org/jira/browse/CASSSIDECAR-499
Project: Sidecar for Apache Cassandra
Issue Type: Improvement
Reporter: Jyothsna Konisa
A single BEGIN BATCH CQL statement that writes to a CDC-enabled table and a
CDC-disabled table under the same partition key, in the same keyspace, produces
one commit log Mutation spanning both tables (Cassandra groups batch writes
this way at the storage-engine level, independent of CDC). CDC bridge's
Schema.instance was only ever populated with CDC-enabled tables and when such a
mixed-table Mutation was read from the commit log, we are seeing unknown table
exception causing mutation loss.
